Claims. (Cl. 248-74) This application is a division of my copendingapplication Ser. No. 540,913, filed June 19, 1944, for Fastening Device,now Patent No, 2,464,620, issued March 15, 1949.

This invention relates to a fastening device comprising a flexible strapor loop and a pair of members adapted to be mounted respectively on theend portions of the loop and coact with each other by snap action tolock the loop closed. One of the objects of the invention is to providethe coacting members of such `form that they be effectively attached tothe strap and will readily coact with each other by snap action when itis desired to close the strap, and will allow separation by a suitableforce, whenever desired.

Another object of the invention is to provide fastening means for theloop effective to hold the loop in different closed positions so that itmay snugly embrace bundles of somewhat different contours. Still anotherobject is to form the device with provision for ready and effectivemounting on a support by an attaching screw.

A preferred embodiment of my invention is illustrated in the drawingshereof and hereinafter described and the essential novel features areset out in the claims.

In the drawings, Fig. l is a perspective of my fastening device in aposition it occupies when attached to a support and embracing an articleor group of articles to be held; the support and articles beingindicated by broken lines; Fig. 2 is a longitudinal section of thefastening device; Fig. 3 is a vertical section on the line 3 3 in Fig.2; Fig. 4 is a horizontal section on the line 4 4 of Fig. 3.

As shown in Figs. l and 2, my fastening device is'very suitable forembracing and holding a bundle of insulated wires illustrated at A. Ashereinafter explained in detail, the device may clamp such bundletightly, even though its external contour varies somewhat. This enablesa tight harness of the wires so that their number may be varied inrepairing or for making an additional installation.

The loop IB, shown in each of the views, has one substantiallytangential end portion I2 and another end portion as I4, projectingdirectly, at substantially a right angle, toward an intermediate regionof the portion l2. The tangential arm of the loop carries one member20vof the fastening device which coacts variously with the other member30 secured to the end ,portion I4. The fastening is adapted to beattached to the support, by a screw as shown at C in Fig. 1, passingthrough the member 20 and into the support B.

As shown, the fastening member 20 has va top portion 2l, return-bendedges 22 and bottom portions 23, s`o that it may embrace the strap arm l2. I preferably reinforce that arm on its underside by a plate 24.Suitable registering bolt openings are provided through the top layer2l; the arm l2; the reinforcing plate, and the bottom portion by centralenlargement of the bottom space, all as indicated by the generalcharacter 25 in Fig. 2. Suitable indentations 2B in the top plate 2lfirmly lock this fastening member to the flexible loop. A tongue 2l isformed at the inner edge of the top plate 2| and extends upwardlytherefrom and is then bent downwardly into a hook 28, Fig. 2, to coactwith the other member 30, as about to be described.

The member 30 has an intermediate portion 3|, return-bend edges 32 andfinal portions 33, so that the device may readily embrace the endportion I4 of the strap and be effectively locked in this position byindentations 36. The member 30 is provid-ed with a plurality of openings3l, 38 which may be occupied by the hooked end 28 of the tongue 21.

Figs. 2 and 3 show the hook 28 engaging the opening 38 in the clip 30and as thus binding a loop of wires A within the loop. To open the loopand free the wires it is merely necessary to press the member 3!!downwardly and inwardly toward the loop arm l2 to free the member fromthe hook. To make a more constricted embrace of the articles to be held,the member 3l] is pressed further inwardly until the hook 28 engages theupper opening 31 of the fastening. I have shown merely two openings,which are to be taken as an indication of any convenient number of morethan one.

With such a construction, the device may be iixedly mounted on asuitable support and is then ready for the reception of what ever is tobe held, as, for instance, a bundle of wires, and then may be snappedtight shut. If it is necessary to remove a wire for repairs (asfrequently happens in airplane work) the release of the member 30 fromthe hook immediately opens the loop and after the injured wire isrepaired, or a substitute supplied, the device may be readily snappedshut. In the original installation, or following the repairs, thelatitude allowed by the multiple anchorages for the fastening hookprovides for the ready embracing of the wires with the snugness desired.

I claim:

l. In a fastening device, the combination of a loop of'iiexible materialhaving projecting end arms, a pair of fastening members each embracing aprojecting arm of the loop, there being registering openings through oneof the fastening members and through the embraced arm of the loop toprovide for the passage of a fastening screw, one of the arms having aprojection adapted to overlap lthe other member,.one of 'fsaidoverlapping portions having an opening and the other overlapping portionhaving a hook adapted to enter` said opening.

2. The combination of a exible loop lhavng separate end arms, afastening device. embracing one end arm and provided with an `openingfor the passage of attaching screw, said 4fastening device having atongue projecting away from the arm and formed with a hookedend, amember embracing the other end arm of lthe 'loop land projecting towardthe arm carrying the firstmentioned fastener said second embracingmember having a plurality of openings, any of which maybeoccupied bysaid hook.

`3. A fastening device comprising a loop of flexible material having onesubstantially .tangential end portionand another endportion proj ectingtoward an intermediate region of the rst mentioned portion, a fasteningmember embracing and secured to the first mentioned end portionpn theouter side of .said intermediate region, a vfastening member embracingand .secured to the second vmentioned end portion, one of said fasteningmembers being .provided withan opening .and the other with a hookadapted to occupy the opening.

4. A fastening device .comprising a loop .of flexible material hav-ingone substantially tangential end portion and another end ,portionprojecting toward an intermediate region of the rst-mentioned portion, afastening member embracing the tangential portion of the loop beyondsaid intermediate region thereof whereby said portion may be secured toa support, said member :having at fits inner end a projectionterminating in 'a`ho`ok, a fastener on the other end portion of the loopprojecting toward said intermediate region and being provided with anopening which =saidhook may occupy.

5. The combination of a exible loop adapted to yembrace an vobject to beheld and having end arms, twofast'ening members secured to said end armsrespectively, one of said fastening members extending 'in the vsamedirection as the loop arm 'to which it is vattached and the otherfastening member having aportion projecting at substantially a rightangle to the loop arm to which it is attached, said portion coactingwith the other fastening member and one of such coacting parts having ahook 'and the other a plurality 4of openings, anyon'e of which maybeoccupied bysaid hook.
